Dyna Form bean properties
Hello,
I'm looking to populate the dyna-form properties back to the form in the
event of a validation failure. It appears that I'll have to use <bean:write
name='key' property='attr' /> tag in the JSP page to assign the values back
into the form fields, but I can't figure out what the name of the bean name
should be. Or, is there another way to do this? If I use plain actionForm
this isn't a problem, since I know the name of the bean. However, this
doesn't seem to work with dynaValidatorForm.
Can someone help?
Thank you,
Scott

DynaActionForm is no different from ActionForm in this respect -- the
property values should already be there for proper redisplay. To prove
it, deploy the standard struts-example app and try to log in with invalid
values (i.e. other than "user" and "pass"). You'll see the form
redisplayed, along with the error messages, with the username
pre-initialized to what you entered (passwords are deliberately not
redisplayed to avoid security risks of someone seeing what you typed when
viewing the page source).
One thing to watch out for -- if you are using request-scope form beans,
and you're doing a redirect (instead of a forward), that will not work --
a redirect causes a second request to occur, so the request scope
attributes are lost.
